If holding your breath underwater for 2min 20 seconds isn’t hard enough, Visser accomplishes this after blowing out all of his air and swimming 50 meters across a pool. While Mark claims he can hold his breath underwater for more than 5 minutes, this particular stunt is freakishly impressive due to distance he covers after expelling all of his oxygen reserves.

With training like this it’s no wonder that this madman received 3 nominations for the XXL awards in his first year of big wave competitions alone.. not to mention many others since.
